         2 . The base frame according to  claim 1 , wherein the bows are secured to an underside of a steel floor in the front end of the base frame and that the gooseneck rails are secured to ridges or tops of the bows. 
     
     
         3 . The base frame according to  claim 1 , wherein the bows are secured to an underside of a steel floor in the front end of the base frame and that the gooseneck rails are provided with cut-outs substantially corresponding to the shape of the bows. 
     
     
         4 . The base frame according to  claim 2 , wherein the goose-neck rails are secured to the bows by welding. 
     
     
         5 . The base frame according to  claim 1 , wherein the bolster is provided with a shelf portion, which shelf portion is placed in a distance from the door sill for supporting an end of a floor plate, which distance is a module of full and half lengths of a floor plate. 
     
     
         6 . The base frame according to  claim 5 , wherein the shelf portion is formed by an end of the steel floor of the gooseneck part of the container. 
     
     
         7 . The base frame according to  claim 5 , characterised in that wherein the shelf portion is formed by the bolster. 
     
     
         8 . The base frame according to  claim 5 , wherein the shelf portion is supported by a number of bolster gussets. 
     
     
         9 . The base frame according to  claim 5 , wherein the shelf portion is formed by an L-shaped profile, which profile is fastened to a number of gussets supporting the bolster. 
     
     
         10 . The base frame according to  claim 5 , wherein the steel flooring is provided with a nose portion in form of a slight downwards sloping end of the floor facing the rear end of the container, which sloping is in an interval including 1 to 10° in relation to the floor. 
     
     
         11 . The base frame according to  claim 5 , wherein the steel floor is fully welded to the bottom side rails and to a front sill. 
     
     
         12 . The base frame according to  claim 1 , wherein a distance between bows are greater for bows placed at an end of a gooseneck tunnel facing a front sill of the base frame than bows placed in the end of the gooseneck tunnel facing the bolster. 
     
     
         13 . A base frame for a shipping container, comprising:
 a front end and a rear end separated by a bolster, the front end of the base frame comprising a pair of bottom side rails or beams and a pair of gooseneck rails or beams positioned in a longitudinal direction of the container, the rear end of the base frame extending from a door sill to the bolster where the gooseneck rails extends continuously from a front sill to the bolster, wherein a number of bows extends continuously from a bottom side rail in one side of the front end of the base frame to a goose neck rail.   
     
     
         14 . A base frame for a shipping container, comprising:
 a front end and a rear end separated by a bolster, the front end of the base frame comprising a pair of bottom side rails or beams and a pair of gooseneck rails or beams positioned in a longitudinal direction of the container, the rear end of the base frame extending from a door sill to the bolster, where the gooseneck rails extends continuously from a front sill to the bolster, wherein between the gooseneck rails and the bottom side rails at each side of a gooseneck tunnel an outrigger rail is placed, which outrigger rails are substantial parallel with the gooseneck rail and the bottom side rails.   
     
     
         15 . The base frame according to  claim 14 , wherein an outrigger is provided between the bottom side rail and an outrigger rail and an outrigger is provided between the outrigger rail and the gooseneck rail. 
     
     
         16 . The base frame according to  claim 14 , wherein the outriggers are shaped as L-profiles. 
     
     
         17 . The base frame according to  claim 14 , wherein the outriggers form a closed profile with a floor where the floor forms one side of the closed profile.
